The mass was easily palpated and moved freely in each direction beneath the skin. There was not sign of dyspnea. Radiographs were taken of lateral and cranio-caudal views, and there was a mass with soft tissue density. Other clinical signs were not mentioned.

The mass was removed surgically by an anesthesia of Ketamine (30 mg/kg) and Diazepam (1.7 mg/kg) intramuscularly. The mass easily detached from the skin but it attached to underneath tissues. The wound was sutured by Nylon 3-0.Antibiotic and multivitamins were administered orally.

The mass was a 2 cm in diameter capsulated abscess that has got a yellowish caseous (cheesy) exuda. Microbiologically Pseudomonas (spp) was isolated pure.
